Energy Efficiency

Energy efficiency means doing the same job with less energy. Potential savings from energy efficiency number in the trillions of dollars, and would cut air pollution by 1.1 gigatons by 2020, the same amount produced annually by the entire US fleet of passenger vehicles and light trucks.

The idea of a smart grid promises to take energy efficiency to another level. By computer, an entire household would be in communication with all power sources. Solar panels on your roof would plan power use for the dishwasher, while your house tells the electricity grid how much heat and light it will need in the next six hours.
